In the world of Type-Moon, it all begins with becoming Morgan's husband!

"If we really want to explain, it actually has something to do with your mother."

“My mother?” Mordred blinked her beautiful green eyes.

"Do you mean the older woman or the younger woman?"

For Mordred, Artoria, who raised her by the sacred lake, was a mother, as was Morgan, who bestowed upon her the title of Knight of the Round Table in Camelot.

“It’s all related.” Ian gripped Mordred’s hand tightly, as if he had grasped at some regret.

"You can think of it as 'it is because of their existence that babies were born.'"

"Eh?"

Mordred frowned slightly, looking even more confused.

"I still don't quite understand."

"Father... could you put it more simply?"

“Then you can take it as my own atonement,” the man said. “A very good girl suffered unnecessary pain because of me.”

"And bb is the embodiment of this pain."

"I...I have to keep her here."

"..."

Mordred still didn't understand.

But she could sense that her usually resolute father was becoming somewhat saddened by this issue—so let's not continue.

I'm not here to be his heartless little cotton-padded jacket.

“Okay, I understand.” Mordred rubbed her cheek against Ian’s arm and confessed her feelings.

"If Father has any problems in the future, he must tell me immediately."

"I...I will do everything in my power to help my father!"

"Little Mo, you've matured a lot," Ian praised his daughter, feeling a little better.

But at this very moment—

Something unexpected happened.

The lights nearby began to flicker, making it look like a scene from a horror movie.

"What, what happened?!"

Mordred tensed up and immediately drew her sword, Clarent, putting herself on high alert.

She may not be as capable as her father, but her desire to protect him will never waver.

What Mordred didn't know was that Ian was worried about something else entirely.

That means there might be something wrong with the baby.

This is no joke.

Ian had witnessed BB's amazing abilities.

Combined with Olga Marie's earlier record—this phenomenon only occurred when she was agitated.

After all, her true form is a super AI, and the channels through which she expresses emotions are naturally things that AI can access.

The man's premonition soon became a reality.

A few seconds after the lights flashed, BB's eyes regained their light, a sign that her consciousness had returned.

but--

Unlike her confident demeanor at the beginning, she now seemed to have suffered a severe blow.

Not only could he not even maintain the most basic standing posture, but he also started to sway and was about to fall backward!

While Mordred was still on guard, wondering what was happening, Ian rushed forward and grabbed BB in a big hug.

"Xiao Mo, hurry and find Dr. Roman!"

Although he hadn't quite grasped what was going on, Mordred nodded quickly the moment he heard his father's order.

She sheathed the radiant and magnificent sword, Clarent.

"I see!"

Ten minutes later.

Ian and BB were alone in a room in the Chaldea medical facility.

After examination with existing instruments, BB's condition was determined to be insufficient magic power after being hit.

That's right.

Although she is essentially a super AI that came here in response to Sakura Tohsaka's wish.

However, because she was actually born after a strong connection with the "Holy Grail," the foundation of her existence is actually a rather special "Servant."

"This is where……"

BB's weak voice reached Ian's ears.

"Babble!" The man grasped her hand. "What's wrong with you?"

"I……"

BB seemed eager to answer Ian's question, but due to insufficient magic, even speaking seemed to become somewhat difficult.

no solution anymore.

As a Master who has already summoned two Servants, Ian knows the best way to solve the problem of insufficient magical energy.

He immediately started unbuttoning the baby's clothes, his movements appearing rough and hurried.

"What... are you doing?" BB said weakly.

"Is there even a question?" Ian pulled BB's clothes open to both sides, exposing her to the same extent as during their first time having sex.

"BB, make a contract with me—become a super AI that only obeys my commands."

"...Haven't they already become that?"

“No.” Ian grabbed BB’s hands and shoved himself right in front of her. “That’s not enough.”

"You must become my servant, or else—you will disappear right now."

"I won't allow that to happen, you understand?"

The man's breath was hot and incredibly close, repeatedly stirring BB's heartstrings.

She felt herself becoming somewhat infatuated.

"You pig...do you really want to do this?"

“Yes.” Ian began rubbing BB’s most embarrassing spot without waiting for a reply. “Just promise me now—and then you can just lie there.”

"I'll take care of the rest."

"..."

BB blushed and nodded.

“BB understands—please enter into a contract with me.”

"Become the owner of BB."

As she spoke, the girl unlocked her core functions, recognizing Ian as someone who could use all permissions without needing her consent.

Ever since——

Thus, a rather unique Servant Contract was born.

To be precise, this wasn't a proper Servant summoning; it was only because of the existence of the "Holy Grail" as a special vessel that Ian and BB used the form of a Servant summoning.

After sensing that the channel for transferring magic between himself and BB had been fully opened, Ian once again displayed his wildness.

As he suckled at her proud breasts, he repeatedly thrust his massive member against her clitoris, causing the mischievous demonic AI to moan incessantly.

Gurgling.

The man's magician's essence accumulated inside the girl's body, forming a sculpted, voluptuous lower abdomen.

I don't know how much later.

Looking at Ian, who was panting heavily but still holding her in his arms, BB felt a surge of warmth in her heart.

"You...you're working really hard."

"Was it good?" the man suddenly asked.

"Huh?" BB was stunned for a moment, then realized what she meant. "You pig—!"

"Hey, hitting your own master isn't a good thing."

Ian grabbed BB's hands, one on each side, and their eyes met.

"..."

"..."

The two of them just stared at each other, and then laughed at the same time, their lips slowly approaching each other and then separating again.

"You're finally alright."

Ian looked at the girl beneath him and breathed a sigh of relief.

"If you can't do it, there's no need to force yourself. You look so pathetic right now."

"Um?!"

Upon hearing this, BB immediately became anxious.

"But BB has already fixed that system!"

"Now—it allows you and that girl named Fujimaru Ritsuka to be teleported out together!"

"Don't underestimate BB, who is a super AI, okay?"

"This……"
